A smart ball-machine uses artificial intelligence to train a player or to play with a player. For example, the ball-machine can adjust the tennis ball speed, topspin, bounce according to the player's successful ball return rate. The ball-machine can be preconfigured with a profile of a player. For example, the ball-machine may download a complete profile of a tennis player from a game recording, or may download a file with a customized profile of a player to train a player using the ball-machine. The ball-machine is equipped with a plurality of wheels, motors, and shafts to provide a fully customizable launch of one or more balls. For example, the ball can be launched from the machine from one side of a tennis court to another side of a tennis court with a variety of speeds, trajectories, topspin, bounce etc.

A computer-implemented method for adapting a training program of a user, including: storing a database including measurement data of physical exercises the user has performed, the measurement data including at least one of heart activity measurement data and motion measurement data; receiving a user input to select a weekly template for the training program, the weekly template including a training schedule including a plurality of pre-programmed repeating exercises on the weekly template; receiving a user input indicating a repeating exercise the user indicates to perform outside the training program; acquiring, from the database on the basis of the user input indicating the repeating exercise, measurement data of past one or more physical exercises of the repeating exercise; determining, on the basis of the measurement data, a training effect of the past one or more physical exercises and determining at least one repeating physical exercise of the training schedule providing a training effect closest to the training effect of the past one or more physical exercises; adapting the training schedule by replacing the determined at least one repeating physical exercise of the training schedule with exercises of the repeating exercise the user indicates to perform outside the training program; and outputting, via a user interface, instructions for the user to follow the adapted training schedule.

In an embodiment, a rehabilitation support system includes: a sensor data acquirer configured to acquire biometric information on a user measured by a sensor; an estimator configured to estimate a state of the user based on the biometric information; a first determiner configured to determine whether the state of the user estimated by the estimator has occurred within a set time, the set time comprising a time slot defined for implementation of a rehabilitation; a first storage device configured to store a mode of a spatiotemporally changing item; a selector configured to select the mode of the spatiotemporally changing item, in accordance with a result of the determination by the first determiner; and a presenter configured to present the mode of the spatiotemporally changing item selected by the selector.

A basketball launching system for recording shooting statistics in association with locations other than passing locations. Controller(s) receive data from a user interface indicating selection of a pass location and one or more shooting locations which are spaced apart from the pass location and program a launching device to pass basketballs to a location at a basketball playing area corresponding to the selected pass location and record shooting performance information in association with an associated one of the selected shooting locations for each respective one of the passes.

An Internet of Thing (IoT) device includes a camera coupled to a processor; and a wireless transceiver coupled to the processor. Blockchain smart contracts can be used with the device to facilitate secure operation.

An exercise rating and improvement system comprising: a feature amount extraction unit for extracting, from information obtained from a subject, a feature amount about exercise efficiency; an rating unit for rating exercise efficiency of the subject by comparing the extracted feature amount and a feature amount to be compared; and an improvement information providing unit for providing, on the basis of the rating result, information such that the feature amount of the subject approaches the feature amount to be compared.

An electronic device and method for personalized fitness activity training using augmented-reality based avatar are provided. The electronic device receives a first set of images of a first user. The first set of images is captured for a duration in which the first user is engaged in a first fitness activity. The electronic device generates an augmented-reality display that includes a first avatar and an image of the first user based on the first set of images. The electronic device further controls a display device to render the generated augmented-reality display. The electronic device further determines posture information of the first user based on the first set of images. The electronic device determines real-time feedback based on application of a first neural network model on the determined posture information. The electronic device controls the first avatar to output the determined real-time feedback in the augmented-reality display.

A system and method for evaluation, detection, conditioning, and treatment of neurological functioning and conditions which uses data obtained while a person is engaged in simultaneously in a range of primary physical tasks combined with defined types of associative activity, such as listening, reading, speaking, mathematics, logic puzzles, navigation of a virtual environment, recall of past stimuli, etc. The data from the physical and associative activities are combined to generate a composite functioning score visualization indicating the relative functioning of areas aspects of neurological functioning; including those in which deficiencies may be present, which are early indicators of possible neurological conditions. Through algorithmic recommendations combined with expert and user input, a conditioning regimen targeting neurological aspects of interest paired with periodic testing allows the user to track their progress in these areas over time.

An offloading system for use with a treadmill includes an air chamber configured to be selectively inflated between a deflated condition and an inflated, operating condition, a user seal coupled to the air chamber and adapted to receive a user so that, in the operating condition, at least a portion of the user is received in the user seal and positioned within the air chamber, a pump operable to inflate the air chamber, and a controller configured to determine an occurrence of a loss of pressure in the air chamber and, in response to the occurrence, cause a reduction of speed of a running belt of the treadmill.

A multi-mode athleticism movement measurement system includes an athlete-borne acceleration sensor and an athleticism processing device to determine athleticism information based upon one or more timing measurements from the athlete-borne acceleration sensor, the athleticism information corresponding to any of multiple athleticism measurement modes available on athleticism processing device and selectable by a user. A data link between the athlete-borne acceleration sensor and the athleticism rating processing device transmits the one or more timing measurements from the athlete-borne acceleration sensor to the athleticism rating processing device.
